C / C++ / MFC

You can use Visual Studio for writing C++ applications targetting the Windows platforms. If you are using UNIX (or Linux) then you are NOT using Visual Studio (and you are using a UNIX or Linux compiler, e.g. gcc). SQL commands are used to deal with databases, see, for instance the SQL Wikipedia page[^]. THESE PEOPLE REALLY BOTHER ME!!

The result of that part of the condition would be the same as static_cast(system[index].name) The string literal will be evaluated but the result of the comma operator is always the leftmost argument. (You probably know that, but I thought I should offer an explanation for less experienced readers) My guess is this was supposed to be a string comparison. Not that it makes the condition look any better... Oh, and btw., I know that '??!' is the trigraph for '|', but I'm not familiar with '?!?'. Typo? ;P GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them.

Have you considered the possibility of a comment line containing a trigraph? See for example this article[^] on curious errors caused by accidental introduction of trigraphs in comment lines.

Might you try changing to a CListCtrl (that has a built in header)? or maybe add a CHeaderCtrl object just above the list box?

Ideally, you'd want minimal exposure, to ensure low coupling. The original post made a point of only showing Param in the private section, and said the user of the library should not be playing around with Param, so I assumed it was not a public type. If the Param type was a public type used in the interface, the best solution would be to include Param.h in libApi.h instead of introducing a new file.

Do not use encryption for passwords. You should add a salt value and use the two pieces of data to create a one-way hash which you store in your database. Remember, encrypted data can be decrypted, hashes cannot. There are many articles and samples explaining this in detail, including Secure Password Authentication Explained Simply[^].

Yes, that's a good question: if you don't want to loose your changes every time your program exits then you have to use permanent storage, that is the hard disk (or another persistent medium like, for instance, flash memory of pen drives). Since you don't want to use a text file, I suppose a binary file is OK for you. You could design your own protocol or use object serialization. If you are using MFC, then you are lucky, since such framework provides good support to serialization, see "Serialization in MFC"[^]. THESE PEOPLE REALLY BOTHER ME!!

Hello Richard, "buttonX" applies to all buttons.

ok. so the binary form is stored in the string. and the i will make a for loop that will count the number of 1's in the binary form of each entered minterms. my problems is how do I group together the minterms with the same number of 1's cause i need to compare 2 different groups later.

I know what: I replaced "(" by "[" in pBuffer = new unsigned char(nSize); ex pBuffer = new unsigned char[nSize];

I noticed something: in order to work correctly, before I change the aligment style, I have to setup scrollbars of list control to top/bottom ... orelse, the list looks uggly (all items are bad drawned) ... it is logical to happend that ? I am thinking that if I setup vertical scrollbar on some position, if I change the aligment style to horizontal, it doesn't fit at he same horizontal position ...

You could use bind1st if CallBackFunc took one parameter: void CallBackFunc(int) { ... } ... obj->SetCallback(std::bind1st(std::mem_fun(&MyClass::CallBackFunc), this)); Since it takes nothing, you may have to write your own function template that takes a callable and a pointer that returns a small function object that stores the callable and the pointer as members and invokes them with operator(): as always, by refusing to use boost you're forcing yourself to reimplement parts of it.

Off the top of my head, one thing that may cause this message would be if you #include the header in multiple locations and have no header guards (either pragma once directive or #ifndef/#define/#endif method).
